She goes to get spayed on 4/14. I'm kinda scared tho

Her brother ("Max") from the same litter was purchased by a friend so we get regular updates. She took him to get neutered & they had to stop surgery because his heart rate & oxygen dropped. We have the same vet & he is the same size as Pippi. I'm scared they're going to have the same problem with her

Anyone have a very tiny yorkie that got successfully "fixed"?!
